1 Chapter 9 Fundamentals of Research

2 Experimental Research A deliberate manipulation of a variable to see if corresponding changes in behavior result, allowing the determination of cause-and-effect relationships Example Hypothesis: Violent TV Programs cause Children to be More Aggressive

3 The Experiment: Variables Independent Variable=manipulated Dependent Variable=measured What is the IV (& DV)?  Light or No Light  Plant Growth What is the IV (& DV)?  Aggression  Violent TV Or No Violent tv

4

5 Levels of Measurement

6 The Experiment: Groups Experimental Group=Treatment Control Group=no treatment Which Group should watch violent tv?  Experimental  Control Experimental GroupControl Group

7 The Importance of Randomization  Random Assignment

8 Experimental Hazards  Placebo Effect -Single/Double Blind Procedure  Experimenter Effect  Hawthorne effect

9 Confounding & Extraneous Variables

10 Evaluating Results  Significant Outcome

11 External & Internal Validity Pair Share: Explain the relationship between internal validity & extraneous variables.

12 Post-Facto Research Study Time Exam Scores Party Time -0.6321 Measuring the relationships between 2 variables
